Status epilepticus is a medical emergency associated with significant mortality and morbidity, which requires immediate and effective treatment. ⋯ Lorazepam is better than diazepam or phenytoin alone for cessation of seizures and carries a lower risk of continuation of status epilepticus requiring a different drug or general anaesthesia. Both lorazepam and diazepam are better than placebo for the same outcomes. In the treatment of premonitory seizures, diazepam 30 mg in an intrarectal gel is better than 20 mg for cessation of seizures without a statistically significant increase in adverse effects. Universally accepted definitions of premonitory, early, established and refractory status epilepticus are required.

Review Meta AnalysisOpioids for neonates receiving mechanical ventilation.
Mechanical ventilation is a potentially painful intervention widely used in neonatal intensive care units. Since newborn babies (neonates) demonstrate increased sensitivity to pain, which may affect clinical and neurodevelopmental outcomes, the use of drugs which reduce pain might be very important. ⋯ There is insufficient evidence to recommend routine use of opioids in mechanically ventilated newborns. Opioids should be used selectively, when indicated by clinical judgment and evaluation of pain indicators. If sedation is required, morphine is safer than midazolam. Further research is needed.

Anticonvulsant drugs have been used in the management of pain since the 1960s. The clinical impression is that they are useful for chronic neuropathic pain, especially when the pain is lancinating or burning. ⋯ There is evidence to show that carbamazepine is effective but trials are small.

Review Meta AnalysisAntibiotic treatment for Clostridium difficile-associated diarrhea in adults.
Clostridium difficile (C. difficile) is recognized as a frequent cause of antibiotic-associated diarrhea and colitis. ⋯ Current evidence leads to uncertainty whether mild CDAD needs to be treated. Patients with mild CDAD may resolve their symptoms as quickly without treatment. The only placebo-controlled study shows vancomycin's superior efficacy. However, this result should be treated with caution due to the small number of patients enrolled and the poor methodological quality of the trial. The Johnson study of asymptomatic carriers also shows that placebo is better than vancomycin or metronidazole for eliminating C. difficile in stool during follow-up. If one does decide to treat, then two goals of therapy need to be kept in mind: improvement of the patient's clinical condition and prevention of spread of C. difficile infection to other patients. Given these two considerations, one should choose the antibiotic that brings both symptomatic cure and bacteriologic cure. In this regard, teicoplanin appears to be the best choice because the available evidence suggests that it is better than vancomycin for bacteriologic cure and has borderline superior effectiveness in terms of symptomatic cure. Teicoplanin is not readily available in the United States, which must be taken into account when making treatment decisions in that country.

Review Meta AnalysisCyclosporine for induction of remission in Crohn's disease.
Cyclosporine was first found to be an effective and well-tolerated immunosuppressive agent in organ transplant recipients, and subsequently in several autoimmune diseases. It was reported in open studies that cyclosporine is effective for induction of remission in Crohn's disease. Four randomized controlled trials have been performed to determine whether the results observed in these open studies were valid. This systematic review summarizes the evidence on the use of oral cyclosporine for the induction of remission in Crohn's disease. ⋯ Brynskov 1989a enrolled a small number of patients and the modified clinical grading scale used in the study has not been validated in other studies. Furthermore, statistically significant clinical improvement does not imply induction of clinical remission. Indeed, Brynskov 1989a found no statistically significant differences in the mean Crohn's Disease Activity Index score at 12 weeks indicating that cyclosporine was no more effective than placebo for induction of remission in Crohn's disease. The results of this review demonstrate that low dose (5 mg/kg/day) oral cyclosporine is not effective for the induction of remission in Crohn's disease. Patients treated with low dose oral cyclosporine are more likely than placebo treated patients to experience adverse events including renal dysfunction. The use of low dose oral cyclosporine for the treatment of chronic active Crohn's disease does not appear to be justified. Oral dosing at higher levels or parenteral administration of cyclosporine have not been adequately evaluated in controlled clinical trials. Higher doses of cyclosporine are not likely to be useful for the long-term management of Crohn's disease because of the risk of nephrotoxicity and the availability of other proven interventions.
